报告内容摘要：

Li-ion batteries are the critical enabling technology for the portable devices, electric vehicles (EV), and renewable energy. However, the safety of current batteries still needs to be improved to satisfy these requirements. The safety concern mainly comes from the flammable organic electrolytes. Alternatively, aqueous electrolyte and solid electrolyte are attracting intensive attention due to their intrinsic non-flammability. In this talk, my previous works on the regulating the electrolyte structure will be introduced. I systematically investigated the relationship between the electrolyte solvation structure and the electrochemical stability window of the electrolytes, interface/interphase stability, as well as the cell reversibility. Several methods that could tuning the solvation cages, both liquid and solid, will be demonstrated. The critical issues limiting these safe electrolytes will be discussed.
